SPECIFICATION forming part of Letters Patent No. 521,236, dated June 12,1894:. Application filed December 18,1893- flerial No. 494,007. (Nomodel.)

To aZZ whom it may concern: n

Be it known that I, JOSEPH GRI'JNINGER, a citizen of the United States,and. a resident of New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements inNewspaper-Files, of which the following is a full and exact description.

My invention relates to improvements in newspaper files such as are usedfor clamping or fastening newspapers therein, so that no single numbersor parts of a number can be lost.

The invention relates principally to a novel and very practical springand. to its combination with the other parts of the file. It is verywell adapted for fastening easily and safely a great many numbers of thepaper and is especially superior to newspaper files heretofore used.because it is veryeasily operated. and combines strength and reliabilitywith neatness.

My improved file consists of two plain' wooden strips, two parallelsheet metal springs which are connected by a metal rod and a wirespring, besides there is a small device for removing the sheet metalspring whenever a new paper shall be inserted.

The file is illustrated in the accompanying drawings, in which Figure 1,shows the two wooden strips A, A connected by the wire spring B. Fig. 2,is a view of the complete file. Fig. 3, represents the sheet springs C,0 connected by a metal rod D. Fig. 4, is a front view of one sheet metalspring and Fig. 5, is a cross section of the upper part of the twostrips with a wire spring connected thereto. Figs. 4. and 5 representthe respective parts in natural size.

.One of the wooden strips is longer than the other and is shaped at thelower enda. so as to forma handle. To the two wooden strips areconnected at the top the ends e, e of a spring B which is provided witha hook or eyelet b; the latter serves for hanging the file up when it isnot'usedJ This spring consists of one continuous piece of metal wire andits two longer ends or legs are fastened each to one of the woodenstrips so that they are not connected directly by the screws 0, c whichtie the lower ends to the strips. (See Fig. 5.) By means of fasteningthis spring to the wooden strips as above described it is possible toseparate them so as to suitany smaller or larger number of papers. Thisarrangement of fastening the lower ends of the spring further enablesthe user to turn the upper wooden strip A in a plane about ninetydegrees or more without taking the file apart so that the new number maybe fastened on top of the last one. The longer wooden strip is providedwith two wooden screws (1, d which are sharply pointed after leaving thewood. These points pass through the newspaper into the shorter or upperstrip and are as near as possible on the inner side of the lower strip,they serve to hold the paper in exact position.

The sheet metal spring consists generally of two parallel springs whichare connected by a metal rod (see Fig. 3). For exceptionally largenewspapers or periodicals three of the sheet metal springs may beconnected to the metal rod; Fig. 4: shows the exact shape of the spring;it is curved in at Q Where the rod D is fastened for the purpose ofpreventing its clamping parts from being shifted over the wooden strips.The spring is pressed on the wooden strips until the inside of thiscurve rests on the wood as shown in Fig. 2. In this with the upper ends,and -of which one is in reversed position. The lower circular ends f, f,resist the opening device when the spring is taken ofi. If alarge numberof papers are in the file the spring must be taken olf and put on bymeans of an opening device. .Two suitably bent lovers with flat endswill answer, but any other device accomplishing this purpose may beused.

In operating my improved file I proceed as follows: The springsconnected by a metal rod are taken oif the wooden strips, then the upperand shorter wooden strip is lifted ofi the metal points and is turned ina plane about ninety degrees when it will be easy to fasten thenewspapers on the two metal points. Now the upper wooden strip isbrought in its former position again, being held in proper place by thetwo metal points, and the sheet metal spring is pressed on.

By the use of my new spring a greatly improved, strong, reliable andneat newspaper file is obtained.

Having thus described my invention, what I claim therein as new, anddesire to secure by Letters Patent, is

1. A newspaper file consisting of two or more parallel sheet metalsprings which are curved in at the center and connected by a metal rodfastened in these curves, and two wooden strips forming the file, and awire spring provided with an eyelet, the ends of the wire spring beingindependently con- JOSEPH GRUNINGER.
